An unnatural way to win the b2 pawn. I liked my position already. Karel tought 9... Qxb2 lost to 10. Ndb5 but this appeared to be all theory, on the highest level: 10... axb5 11. Nxb5 Ra5 (11...

I had completely missed this one. Black is suddenly winning. 25. Qxg4+ Ka5 26. Qe4 Bxd6 27. Kh1 Rhf8 0-1
